About encrypting data and files on your smartphone

When encryption for data on your
BlackBerry smartphone is turned on, your smartphone uses a
private key to encrypt data stored on your smartphone, including data that
your smartphone receives when it's locked. When you lock your smartphone with a password, a lock indicator appears at the top of the screen when your
smartphone has secured your
data.
You can also encrypt the files on your media card using your smartphone password, an encryption key that your smartphone generates, or both. Your smartphone decrypts data as you access
it.

If you encrypt the files on your media card using an encryption key that your smartphone
generates, you can only access the files when the media card
is inserted into your smartphone. If you encrypt the files using your smartphone
password, you can access the files in any smartphone that you
insert your media card into, as long as you know the smartphone password that was used to protect the files.

If you use a smart card certificate for authentication, depending on
the smart card, you might also be able to use one of your smart card
certificates to provide two-factor encryption. In order to access the encrypted
content, you must provide your smartphone password and also connect your smartphone to
your smart card reader.
